1 Claim.

This invention relates to a condensation trap and it is one object of the invention to provide a device of this character adapted to be mounted in an air line leading from a compressor to one or more beer kegs and serve to catch water formed by condensation. It will thus be seen that this water of condensation will be prevented from reaching the beer kegs and spoiling the taste of the beer in the kegs to which compressed air is supplied in order to force the beer out of the kegs.

Another object of the invention is to so form the condensation trap that air from a condenser may be directed to one or several kegs of beer.

Another object of the invention is toprovide a condensation trap having a housing or casing which is so formed that it may be firmly secured against a wall or other support in an upright position with the air supply pipe from the compressor connected with its top and hoses for delivering air to kegs leading from valves extending from saide walls of the casing near the top thereof. By this arrangement air may flow freely through the casing from the inlet to the outlets and. water of condensation accumulate in the lower portion of the casing.

Another object of the invention is to provide the casing of the condensation trap with a bottom which is removable secured in order thatv the trap may be thoroughly cleaned.

The invention is illustrated in the accompanying drawing wherein:

Fig. 1 is a side elevation of the improved condensation trap. Fig. 2 is a top plan view thereof.

Fig. 3 is a vertical sectional view taken through the trap along the line 3-3 of Figure 2.

Fig. 4 is a fragmentary view in elevation looking at one of the hinged keepers by means of which the bottom is removably held to the body of the casing.

This improved condensation trap has a casing or housing I having its rear wall 2 flat so that it may fit flat against a wall or equivalent support where it is secured by screws or equivalent fasteners passed through ears 3 which project from opposite sides of the rear wall. The casing or housing will thus be secured in an upright position against its support.

The bottom 4 of the casing is formed with a depending central boss 4 having a threaded opening 5 formed therethroughto receive a petcock 6 constituting a drain through which water of condensation is to be drawn oil when necessary and the upper or inner surface of the bottom is dished as shown at I so that water will gravitate towards the outlet. The bottom should be detachable so that it may be removed and the interior of the casing thoroughly cleaned, and in order to so mount it there have been pro- 5 vided arms or hooks 8 pivoted to ears 9 at opposite sidesof the bottom 4. These hooks have bills" H! at their free ends to over-hand tongues or lips II projecting from opposite sides of the casing and through the bills are threaded screws 10 l2 which when tightened bear upon the lips H and draw the bottom upwardly to the closing position where the lower edge portion of walls of the casing will be held in tight compressing engagement with the gasket l3 mounted in the 15 groove I4 of the bottom. By loosening the screws the bottom may be removed after swinging the hooks out of the upright position and after the casing has been thoroughly cleaned with steam or in any other manner desired the bottom will 20 be replaced and again tightly secured.

Air is delivered from a compressor through a pipe l5 having a valve l6 intermediate its length and in order to connect the pipe l5 with the casing there has been provided an elbow'l'! which 25 is screwed into a threaded opening I8 formed through a boss H9 at the center of the top'20 of the casing. A number of outlet openings 2! are formed through the bosses 22 spaced from each other aboutth-e casing near the upper'end 3 thereof. Initially the outlets 2| are closed by plugs 23 which are screwed into the outlets so that they can be removed and valves 24 applied. To these valves are connected pipes 25 for conducting compressed air to the beer kegs. If one 35 keg is in use only one valve and pipe will be connected with the casing but if more than one keg is in use additional valves and pipes will be applied. Itis obvious that when a keg in use is emptied the valve of its pipe 25 will be shut 01f While removing the empty keg and setting another in place. When use of a keg is discontinued its pipe 25 and valve may be removed and the outlet opening closed by a plug 23 or the pipe may be disconnected from the valve shut off. The fact that the air under pressure passes from the pipe I5 into the casing at its top and the outlets are located near the upper end thereof very effectively prevents water of condensation reaching the keg or kegs as any Water of condensation formed in the pipe l5 will drain therefrom into the casing and accumulate in the lower portion thereof where it will be held until drawn ofi through the pet cock 6. 55

Having thus described the invention, what is claimed is:

A condensation trap comprising a casing adapted to be mounted in an upright position, a coupling screwed into an opening formed in the top of said casing centrally thereof and projecting upwardly therefrom for connection with a pipe leading from a source of air under pressure, threaded openings being formed in side walls of the casing near the top thereof, threaded plugs screwed into some of the threaded openings and constituting removable closures for the same, valves screwed into unplugged ones of the threaded openings and projecting outwardly from the casing for connection with distributor pipes, a bottom for said casing formed with a concaved inner surface surrounding a centrally located opening, a drain cock screwed into the opening of the bottom, abutment lugs extending outwardly from walls of said casing adjacent the lower end thereof, hangers pivoted to marginal portions of said bottom for vertical swinging adjustment from a lowered position to a raised position and having bills at their free ends for overhanging said abutment lugs when the hangers are in a raised position, and screws threaded through the bills of said hangers for engaging said abutment lugs and applying pressure thereto to draw the bottom upwardly and firmly hold the bottom in place of closing relation to the lower end of the casing.
